  Interesting, I never even thought about this usecase. But fingerprints can change over long enough timescales, either by accident or simply old age.

    Perhaps, but even with acid burns, computers can still find enough commonality to link them. Fundamentally, a secret is something that needs to be changeable. Since you can't (currently) change your fingerprints on-demand, they can't be used as a good secret.
